Step 1: Gather the Jets, Nozzles and Injector opener tool.

Replacement nozzles and injector suitable for your gas cooker

Wrench or screwdriver (specific to your cooker model)

Cleaning cloth or paper towels

Safety goggles and gloves (for added protection)

Step 2: Turn off the gas supply

Before making any adjustments or modifications, ensure the gas supply to the cooker is turned off. Locate the gas shut-off valve behind the cooker or in a nearby utility area and turn it to the “Off” position.

Step 3: Remove the burner covers and grates

Carefully remove the burner covers and grates from the cooking range. These components may simply lift off or require unscrewing, depending on your cooker model.

Step 4: Locate the nozzles and injector

Identify the location of the existing nozzles and injector. These are typically found at the base of each burner, connected to the gas supply line. Refer to your cooker’s manual or consult the manufacturer’s website for precise instructions if needed.

Step 5: Disconnect the existing nozzles and injector

Using the appropriate wrench or screwdriver, carefully loosen and disconnect the existing nozzles and injector from the gas supply line. Take note of their positions for reference during reassembly.

Step 6: Clean the burner components

Before installing the new nozzles and injector, take a moment to clean the burner components.

Step 7: Install the new nozzles and injector

Take the replacement nozzles and injector and align them with the respective openings on the gas supply line. Carefully tighten them using the appropriate wrench or screwdriver. Ensure they are securely in place but avoid over-tightening, which could cause damage.

Step 8: Reassemble the burner covers and grates

Once the new nozzles and injector are securely installed, reassemble the burner covers and grates. Ensure they are correctly positioned and properly attached according to your cooker’s design.

Step 9: Turn on the gas supply and test

With the adjustments made and everything reassembled, it’s time to turn on the gas supply. Slowly open the gas shut-off valve to restore the gas flow to the cooker. Check for any gas leaks and use a soapy water solution to detect them (bubbles will form if there is a leak). If you notice a leak, turn off the gas immediately and seek professional assistance.

Step 10: Test the flame and make necessary adjustments

Once the gas is flowing, ignite the burners individually and observe the flame. It should be steady, blue, and well-distributed. If the flame appears yellow, uneven, or exhibits any other abnormalities, there may be additional adjustments required. Consult your cooker’s manual or consider seeking professional assistance to fine-tune the flame for
